Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
127 words
A medical retrieval device, comprising: a sheath having a proximal end and a distal end; a handle at the proximal end of the sheath; and a basket for removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath and an expanded position where the basket extends from the distal end of the sheath, the basket comprising a proximal end, a distal end, a cap, and three or more legs, each of the three or more legs comprising a distal end, the distal end of at least one of the legs being inserted into the cap, the cap being distal to the proximal end of the basket, and each of the legs comprising a bend distal to the cap.
Claim 2
Dependent Claim
127 words
A medical retrieval device, comprising: a sheath having a proximal end and a distal end; a handle at the proximal end of the sheath; and a basket for removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath and an expanded position where the basket extends from the distal end of the sheath, the basket comprising a proximal end, a distal end, a cap, and three or more legs, each of the three or more legs comprising a distal end, the distal end of at least one of the legs being inserted into the cap, the cap being distal to the proximal end of the basket, and each of the legs comprising a bend distal to the cap.
Claim 3
Dependent Claim
19 words
The medical retrieval device of claim 1 wherein each of the legs is joined to the cap by soldering.
Claim 4
Dependent Claim
21 words
The medical retrieval device of claim 1 wherein the distal each of the legs is joined to the cap by gluing.
Claim 5
Dependent Claim
13 words
The medical retrieval device of claim 1 wherein the cap comprises a core.
Claim 6
Dependent Claim
48 words
The medical retrieval device of claim 1 wherein the length of the legs is about 0.5 inches to 3.5 inches, the width of the legs is about 0.005 inches to 0.015 inches, and the thickness of the legs is in the range of 0.028 inches to 0.045 inches.
Claim 7
Dependent Claim
16 words

Claim 8
Independent Claim
62 words
A method for manufacturing a basket for a medical retrieval device, comprising: removing from a sheet of material a shape comprising three or more tapered legs, the three or more tapered legs intersecting at a distal end of the basket; and bending the legs to form a distal end of at least a portion of a three-dimensional basket structure for retrieving objects.
Claim 9
Independent Claim
62 words
A method for manufacturing a basket for a medical retrieval device, comprising: removing from a sheet of material a shape comprising three or more tapered legs, the three or more tapered legs intersecting at a distal end of the basket; and bending the legs to form a distal end of at least a portion of a three-dimensional basket structure for retrieving objects.
Claim 10
Dependent Claim
18 words
The method of claim 7 wherein removing the shape comprises stamping the shape from the sheet of material.
Claim 11
Dependent Claim
18 words
The method of claim 7 wherein removing the shape comprises photo-etching the shape from the sheet of material.
Claim 12
Dependent Claim
18 words
The method of claim 7 wherein removing the shape comprises cutting the shape from the sheet of material.
Claim 13
Independent Claim
96 words
A method for retrieving material from a body, comprising: inserting a device into a body, the device comprising a basket comprising a proximal end, a distal end, a cap, and three or more legs, each of the three or more legs comprising a distal end, the distal end of at least one of the legs being inserted into the cap, the cap being distal to the proximal end of the basket, and each of the legs comprising a bend distal to the cap; capturing the material within the basket; and withdrawing the device from the body.
Claim 14
Independent Claim
96 words
A method for retrieving material from a body, comprising: inserting a device into a body, the device comprising a basket comprising a proximal end, a distal end, a cap, and three or more legs, each of the three or more legs comprising a distal end, the distal end of at least one of the legs being inserted into the cap, the cap being distal to the proximal end of the basket, and each of the legs comprising a bend distal to the cap; capturing the material within the basket; and withdrawing the device from the body.
Claim 15
Independent Claim
57 words
A method for manufacturing a basket for a medical retrieval device, comprising: molding a shape comprising three or more tapered legs, the three or more tapered legs intersecting at a distal end of the basket; and bending the legs to form a distal end of at least a portion of a three-dimensional basket structure for retrieving objects.
Claim 16
Independent Claim
57 words
A method for manufacturing a basket for a medical retrieval device, comprising: molding a shape comprising three or more tapered legs, the three or more tapered legs intersecting at a distal end of the basket; and bending the legs to form a distal end of at least a portion of a three-dimensional basket structure for retrieving objects.
Claim 17
Dependent Claim
10 words
